INVENTOR. JOHN R. MARTIN ATTORNE United States Patent 3,494,610 HOLDING DEVICE FOR INTERNAL COMBUSTION ENGINE HEADS John R. Martin, 411 Iowa Ave., Girard, Ohio 44420 Filed Aug. 14, 1967, Ser. No. 660,414 Int. Cl. B25b 1/20 U.S. Cl. 269-16 6 Claims ABSTRACT OF THE DISCLOSURE A device mountable in a vice on a workbench providing extensible and-rotatable mounting members to which a head of an internal combustion engine may be bolted, and providing receptacles for valves from said engine.

The principal object of the invention is the provision of a device for holding internal combustion engine heads at such times as the engines are being repaired and the heads have been removed therefrom.

A further object of the invention is the provision of a device that may be positioned in a vice on a workbench and held thereby while providing extensible and rotatable mounting plates to which engine parts may be conveniently temporarily mounted.

A still further object of the invention is the provision of a device which facilitates the repair of internal combustion engines and particularly the head and valve assemblies thereof, by providing means for mounting the head of the engine in many and various positions facilitating Working on the same, and simultaneously holding and maintaining the prearranged order of the valves from the engine so that the same may be eventually replaced in the engine in the same order in which they were originally found.

The device for holding heads of internal combustion engines while the same are being repaired or worked upon includes an apertured body member with the apertures arranged to receive the individual valves from the engine in a pattern resembling the arrangement of the valves in the engine so that their location and identity may be maintained. It also provides telescopic and rotatable means to which the head may be temporarily attached, which permits the head to be moved into many and various positions to facilitate work on the same. The device itself may be mounted on a workbench as by positioning it on a vice on the workbench.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being the intention to cover all changes and modifications of the example of the invention herein chosen for purposes of the disclosure, which do not constitute departures from the spirit and scope of the invention.

The invention is illustrated in the accompanying drawing, wherein:

FIGURE 1 is a perspective view of the device for holding an internal combustion engine head with broken lines illustrating an engine head in position thereon.

FIGURE is a top plan view of the device for holding an internal combustion engine head.

FIGURE 3 is a front elevational view thereof.

FIGURE 4 is an end elevational view thereof.

By referring to the drawing, and FIGURE 1 in particular, it will be seen that the device for holding internal combustion engine heads comprises an elongated section of square metal tubing formed into a body memher or rigid beam 10. A plurality of transversely and longitudinally spaced openings 11 are formed in the upper surface thereof, and in a number and arrangement corresponding with the number and arrangement of valve re- Patented Feb. 10, 1970 ceiving openings in an internal combustion engine head, so that the valves upon being removed therefrom can be positioned in the openings 11 in the same arrangement as occurred in the head.

Broken lines in FIGURE 1 indicate an internal combustion engine head 12 which is shown in inclined position and attached to a mounting plate 13 which is mounted on the end of a tubular support 14 which in turn is telescopically positioned in a tubular body 15. The tubular body 15 is one of a pair mounted transversely of the body member 10 adjacent the opposite ends thereof, and extending sidewardly therefrom. Each of the tubular bodies 15 is welded to the front and back walls of the body member 10 and each of the tubular bodies 15 is provided with a drilled and tapped boss 16, the drilled opening therein communicating with the interior of the tubular body 15 and adapted to receive a set screw 17 having a winged head configuration by which it may be conveniently manually moved.

Each of the plates 13 on the respective outer ends of the tubular supports 14 is provided with a plurality of longitudinally extending slots 18 so that bolts may be positioned therethrough and engaged in threaded openings in the engine head 12. It will occur to those skilled in the art that the slots 18 permit different heads to be mounted on the plates 13, as they accommodate different bolt hole openings in the heads.

By referring to FIGURE 4 of the drawing, it will be seen that the tubular body 15 extends through appropriately shaped openings in the front and back walls of the body member 10 and is welded thereto, as hereinbefore described.

In operation, the body member 10 is positioned in a vice on a workbench and the vice engaged thereon so that the body member 10 is held in desired position relative to the workbench. One of the set screws 17 is loosened and one of the tubular supports 14 with its mounting plate 13 is moved outwardly sufficiently to enable bolts to be positioned through the slots 18 therein and engaged in the head to be mounted thereon and held thereby. The head so held may then be rotated to a desired position for working on the same and locked in that position by tightening the set screw 17. It will occur to those skilled in the art that two heads may be worked on simultaneously or that other engine parts may be bolted to the other one of the pair of slotted plates 13 provided by the device.

When the engine head has been mounted on the device the valves may be removed therefrom and immediately positioned in the longitudinally and transversely spaced openings 11 in the body member 10, which provide a pattern similar to the arrangement of the valves in the head. Thus, the same valves upon having been cleaned or ground and held by the device in their proper location, may be again returned to the head in the same valve openings in which they were originally positioned in the engine.

It will thus be seen that a device for holding internal combustion engine heads has been disclosed which meets the several objects of the invention, and having thus described my invention, what I claim is:

1. A device mountable in a vice on a workbench for movably positioning and holding a workpiece such as an internal combustion engine head, and comprising an elongated body member having at least one sidewardly extending body, a support telescopically mounted in said sidewardly extending body and mounting means on the end of said support to which said workpiece may be temporarily fastened, and means on said sidewardly extending body for selective engagement with said support to hold the same in predetermined position relative thereto, said elongated body member having means for secure engagement in a vice mounted on a workbench 3 whereby said device and workpiece may be positioned on a workbench for easy access thereto.

2. The device for holding an engine head set forth in claim 1 and wherein said sidewardly extending body comprises a tubular body member positioned transversely of said device and extending outwardly from one side thereof.

3. The device for holding an engine head set forth in claim 1 and wherein said sidewardly extending body comprises a tubular member and said support comprises a secondary tubular member telescopically engaged therein.

4. The device for holding an engine head set forth in claim 1 and wherein said means on said' support comprises an apertured plate.

5. The device for holding an engine head set forth in claim 1 and wherein said device has a plurality of References Cited UNITED STATES PATENTS 1,330,807 2/1920 Ilieff. 1,614,697 1/1927 Snook 26916 X 1,864,305 6/1932 Holmes 269-16 X FOREIGN PATENTS 633,883 12/ 1949 Great Britain.
